The CAD M9 is a c ardioid, single-tube, externally-biased condenser microphone featuring servo-valve technology. It naturally bridges the technologies developed for the VX2 and the M-Series microphones. The head amp in the M9 is a 12AX7 tube in a circuit that is optimized for super-wide dynamic range and low noise. The output stage is a high-speed dual opamp in a balanced differential configuration that allows long cables to be used without affecting mic performance. With 30' professional quality, seven-conductor cable with gold-plated XLR male and female connectors; MV200 analog power supply; line cord; rugged carrying case; suspension shock mount.
Requires phantom power.
